4. T9.3 Underpinnings of the NPV Rule
Why does the NPV rule work? And what does “work” mean? Look at it this way:
A “firm” is created when securityholders supply the funds to acquire assets that will be used to produce and sell a good or a service;
The market value of the firm is based on the present value of the cash flows it is expected to generate;
Additional investments are “good” if the present value of the incremental expected cash flows exceeds their cost;
Thus, “good” projects are those which increase firm value - or, put another way, good projects are those projects that have positive NPVs!
Moral of the story: Invest only in projects with positive NPVs.

18. T9.12 Profitability Index Illustrated
Now let’s go back to the initial example - we assumed the following information on Project X:
Initial outlay -$1,100 Required return = 10%
Annual cash benefits:
Year Cash flows
1 $ 500
,000
What’s the Profitability Index (PI)?

19. T9.12 Profitability Index Illustrated (concluded)
Previously we found that the NPV of Project X is equal to:
($ ) - 1,100 = $1, ,100 = $
The PI = PV inflows/PV outlay = $1,281.00/1,100 =
This is a good project according to the PI rule. Can you explain why?
It’s a good project because the present value of the inflows exceeds the outlay.

20. T9.13 Summary of Investment Criteria
I. Discounted cash flow criteria
A. Net present value (NPV). The NPV of an investment is the difference between its market value and its cost. The NPV rule is to take a project if its NPV is positive. NPV has no serious flaws; it is the preferred decision criterion.
B. Internal rate of return (IRR). The IRR is the discount rate that makes the estimated NPV of an investment equal to zero. The IRR rule is to take a project when its IRR exceeds the required return. When project cash flows are not conventional, there may be no IRR or there may be more than one.
C. Profitability index (PI). The PI, also called the benefit-cost ratio, is the ratio of present value to cost. The profitability index rule is to take an investment if the index exceeds 1.0. The PI measures the present value per dollar invested.

21. T9.13 Summary of Investment Criteria (concluded)
II. Payback criteria
A. Payback period. The payback period is the length of time until the sum of an investment’s cash flows equals its cost. The payback period rule is to take a project if its payback period is less than some prespecified cutoff.
B. Discounted payback period. The discounted payback period is the length of time until the sum of an investment’s discounted cash flows equals its cost. The discounted payback period rule is to take an investment if the discounted payback is less than some prespecified cutoff.
III. Accounting criterion
A. Average accounting return (AAR). The AAR is a measure of accounting profit relative to book value. The AAR rule is to take an investment if its AAR exceeds a benchmark.

22. T9.14 The Practice of Capital Budgeting

23. T9.15 Chapter 9 Quick Quiz
1. Which of the capital budgeting techniques do account for both the time value of money and risk?
2. The change in firm value associated with investment in a project is measured by the project’s _____________ .
a. Payback period
b. Discounted payback period
c. Net present value
d. Internal rate of return
3. Why might one use several evaluation techniques to assess a given project?

24. T9.15 Chapter 9 Quick Quiz
1. Which of the capital budgeting techniques do account for both the time value of money and risk?
Discounted payback period, NPV, IRR, and PI
2. The change in firm value associated with investment in a project is measured by the project’s Net present value.
3. Why might one use several evaluation techniques to assess a given project?
To measure different aspects of the project; e.g., the payback period measures liquidity, the NPV measures the change in firm value, and the IRR measures the rate of return on the initial outlay.

T Solution to Problem 9.3
Offshore Drilling Products, Inc. imposes a payback cutoff of 3 years for its international investment projects. If the company has the following two projects available, should they accept either of them?
Year Cash Flows A Cash Flows B
0 -$30,000 -$45,000
, ,000
, ,000
, ,000
, ,000

26. T9.16 Solution to Problem 9.3 (concluded)
Project A:
Payback period = ($30, ,000)/10,000
= 2.50 years
Project B:
Payback period = ($45, ,000)/$250,000
= years
Project A’s payback period is 2.50 years and project B’s payback period is 3.04 years. Since the maximum acceptable payback period is 3 years, the firm should accept project A and reject project B.

27. T Solution to Problem 9.7
A firm evaluates all of its projects by applying the IRR rule. If the required return is 18 percent, should the firm accept the following project?
Year Cash Flow
0 -$30,000
,000
2 0
,000

28. T9.17 Solution of Problem 9.7 (concluded)
To find the IRR, set the NPV equal to 0 and solve for the discount rate:
NPV = 0 = -$30, $25,000/(1 + IRR)1 + $0/(1 + IRR) $15,000/(1 + IRR)3
At 18 percent, the computed NPV is ____.
So the IRR must be (greater/less) than 18 percent. How did you know?

29. T9.17 Solution of Problem 9.7 (concluded)
To find the IRR, set the NPV equal to 0 and solve for the discount rate:
NPV = 0 = -$30, $25,000/(1 + IRR)1 + $0/(1 + IRR) $15,000/(1 + IRR)3
At 18 percent, the computed NPV is $316.
So the IRR must be greater than 18 percent. We know this because the computed NPV is positive.
By trial-and-error, we find that the IRR is percent.
